Find the slope of the line that is parallel and perpendicular to the following equation.
2x-2y=-6
Answer:
Parallel lines 1
perpendicular lines -1
Step-by-step explanation:
2x-2y = -6
Solve for y to get it in slope intercept form
-2y = -2x-6
Divide by -2
y = x+3
This is slope intercept form y = mx+b where m is the slope
Parallel lines have the same slope
A parallel line would have a slope of 1
Perpendicular lines would have a slope that is a negative reciprocal
-1/1
Perpendicular lines would have a slope of -1
Let us first put it into slope-intercept form ⇒ [tex]y = mx + b[/tex]
m: slopeb: y-intercept of the functionTo put it into that format, we need to simply put y on one side of the equation and the rest on the other side
[tex]2x - 2y =-6\\-2y = -2x -6\\y = x +3[/tex]
What do we want to find first ⇒ a line parallel to the original line
a line that is parallel to the original line only has one requirement, it must have the same slope, such as the one below[tex]y = x +5[/tex]
What do we also want to find ⇒ a line perpendicular to the original line
a line that is perpendicular to the original line only has one requirement, the slope has to be the negative reciprocal of the original slope⇒ original slope is 1 ⇒ negative reciprocal is - 1/1 = -1
⇒ so an example is
[tex]y = -x + 3[/tex]
Answer:
Line that is parallel: slope is 1Line that is perpendicular: slope is -1Hope that helps!
How many solutions does this
equation have?
3s = 8s -5s
A one solution
C no solution
B two solutions
D infinite
Answer:
D
Step-by-step explanation:
3s = 8s - 5s
8s = 8s
s = 0, 1, 2, 3.......
so infinite solutions
D)
Step-by-step explanation:Given equation:
[tex]3s = 8s - 5s[/tex]To simplify this equation, we need to isolate the variables on one side of the equation and the constants on the other side of the equation. To do this, we can simplify the R.H.S as like terms can subtract.
⇒ [tex]3s = 8s - 5s[/tex]
⇒ [tex]3s = s(8 - 5)[/tex]
⇒ [tex]3s = s(3) = 3s[/tex]
⇒ [tex]3s= 3s[/tex]
Since both sides of the equation are the same, this system of equations has infinite solutions.
Check:We can check our answer by substituting the value of "s" into the equation. As a result, you will see that many values of "s" are satisfying the equation. Thus, Option D is correct.

What is negative correlation?
Correlation is a statistical measure used to measure the relationship that exists between two variables.
Negative correlation means that the two variables move in opposite directions. If one variable increases, the other variable decreases. When there is a negative correlation, the graph of the variables is downward sloping

Justine has $13.50 left on her city bus card and each bus ride cost $2.25.what equation can be used to find the number of bus rides he has left
Answer:
6 rides
Step-by-step explanation:
Total balance = $13.50 = ($2.25/ride)x, where x is the remaining number of rides. Dividing both sides by $2.25/ride yields 6.
Justin has enough on his bus card for 6 more rides.
An angle measures 142° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
161° and 19°
Step-by-step explanation:
supplementary angles =180
(142+x)+(x)=180
142+2x=180
2x=180-142
2x=38
x=19
142+19=161
How to solve [tex]2n =\frac{15}{2}[/tex] and [tex]\frac{1}{4} =\frac{n}{5}[/tex] ???
Answer:
[tex]2n=\dfrac{15}{2}[/tex]
Multiply both sides by 2:
[tex]\implies 2 \cdot 2n=2 \cdot \dfrac{15}{2}[/tex]
[tex]\implies 4n=15[/tex]
Divide both sides by 4:
[tex]\implies \dfrac{4n}{4}=\dfrac{15}{4}[/tex]
[tex]\implies n=\dfrac{15}{4}[/tex]
[tex]\dfrac14=\dfrac{n}{5}[/tex]
Multiply both sides by 5:
[tex]\implies 5 \cdot \dfrac14=5 \cdot \dfrac{n}{5}[/tex]
[tex]\implies \dfrac54=n[/tex]
[tex]\implies n=\dfrac54[/tex]
Answer:
Step-by-step explanation:
2n = 15/2
Divide both sides b y 2:
n = 15/2 / 2
= 15/2 * 1/2
= 15/4.
1/4 = n / 5
Multiply both sides by the LCM (20):
20/4 = 20n/5
5 = 4n
n = 5/4.

1. Given the following coordinates, complete the listed transformations in sequence, which means you do one after the other.
X(2, 4)
Y(5,-3)
Z(-7, 1)
a) Rotate the points 90 degrees clockwise
b) Dilation by a scaling factor of 2
c) Reflect across the x-axis
d) Translation 2 Up and 5 to the Left
Transforming the points involves changing their coordinates
The image of the points are: (3, 6), (-11, 12) and (-3, -12)
How to complete the transformations?The coordinates of the points are given as:
X(2, 4)
Y(5,-3)
Z(-7, 1)
a) Rotate the points 90 degrees clockwiseThe rule of this transformation is:
(x, y) to (y, -x)
So, we have:
X' = (4, -2)
Y' = (-3, -5)
Z' = (1, 7)
b) Dilation by a scaling factor of 2The rule of this transformation is:
(x, y) to (2x, 2y)
So, we have:
X'' = (8, -4)
Y'' = (-6, -10)
Z'' = (2, 14)
c) Reflect across the x-axisThe rule of this transformation is:
(x, y) to (x, -y)
So, we have:
X''' = (8, 4)
Y''' = (-6, 10)
Z''' = (2, -14)
d) Translation 2 Up and 5 to the LeftThe rule of this transformation is:
(x, y) to (x -5, y + 2)
So, we have:
X'''' = (3, 6)
Y'''' = (-11, 12)
Z'''' = (-3, -12)
Hence, the image of the points are: (3, 6), (-11, 12) and (-3, -12)
